Director James Wan revealed its name

We now have an official title for the sequel to 'Aquaman'.

The first 'Aquaman' hit cinemas back in 2018, revealing the origins of the superhero played by Jason Momoa.

The 'Game of Thrones' star first played the half-Atlantean, half-human in 'Justice League' and reprised the role earlier this year in the re-cut, 'Zack Snyder's Justice League'.

Momoa will be deep diving again in the superhero movie sequel titled... *drum roll*... 'Aquaman and the Lost Kingdom.'

James Wan, who directed the first movie and will helm the follow-up, revealed the name on Instagram.

Cameras haven't started rolling on the film yet, but they are having production meetings for it.

Wan captioned his post: "The tide is rising."

Little is known about the plot at this point. The title suggests we can probably expect more underwater action.

David Leslie Johnson-McGoldrick (who collaborated with Wan on the first 'Aquaman' and 'The Conjuring 2', and wrote the new movie 'The Conjuring: The Devil Made Me Do It') is penning the script for 'Aquaman and the Lost Kingdom.'

Aside from Momoa, Amber Heard will be back as Mera and Patrick Wilson is returning as Orm.

'Aquaman' stars Willem Dafoe, Nicole Kidman, Yahya Abdul-Mateen II and Dolph Lundgren are also returning.

Momoas's 'Game of Thrones' co-star Pilou Asbæk, who played Euron Greyjoy, is in talks to join them.

Filming commences next month in Hawaii.

'Aquaman and the Lost Kingdom' currently has a release date of December 16, 2022.
